the CTR profile is what it is, slim and functional. lock lever holds the position with zero rock. integrated QD socket is positioned right for a single point sling from the carrier shoulder strap
CTR locks tight against the buffer tube with the friction lever engaged, zero wobble. FDE on mine is the standard magpul FDE, matches a magpul MOE grip exactly. cheek weld is fine for irons or LPVO use
